TE STATES PATENT ILLINOIS;

Specification of Letters Patent. Application filed July 29, 1912. Serial No. 712,020.

Patented Feb; 4, 1913.

' the following is a specification.

My present invention pertains to plasters; and it contemplates the provision of a plaster which by reason of its form is adapted to conform and closely adhere to the foot so as to present a smooth surface, and One free from wrinkles over a bunion and between the foot and the sock or stocking of the erson afilicted w ththe bunion.

- ith the foregoing in mind the invention will be fully understood from the following description andclaim when the same are read in connection with the drawings accompanying and forming part of this specification, in which: I

Figure 1 is a plan of my novel bunion plaster as the same appears when placed on the market and precedent to being applied to the foot over; a bunion. Fig. 2 is a transverse section-taken in the plane indicated by the line 22- of Fig. 1.

Similar numerals of reference desi nate corresponding parts in all views 0 the drawings. I

My novel plaster comprises an adhesive and medicinal layer 1, and a protective layer 7; thelatter being ermanently joined to the adhesive layer by t e character thereof, and being preferably, though not necessarily, formed of a suitable textile material.

The essence of my invention resides in I the form and construction of the plaster,

and by reference to Fig. 1, it will be manifest that the plaster is of generally squareconfiguration, and that it comprises four petals joined together at the center of the plaster. Each of the said petals is rovided with rounded corners, as indicate by 3, and is gradually diminished in" width from the said corners, to the point where the petal merges into the central rtion 4 of the plaster. It will also be mani est from "Fig.1 that thewouter portions of the op-- posed edges of the petals rest quite close together, as indicated by 5, and that tween the saidouterportions 5 and the central portion 4 the'edges of the petals are cut away to form apertures 6,,wh1ch are materially advantageous, as. hereinafter set fort By virtue of the provisionof the apertures 6, any fullness of the plaster due to overlapping of the petals or any portion thereof is obviated. Moreover by means of the capacity of the petals to he overlapped, the plaster can be made to readily fit any I raancrsrugpx, prcggpepo, rnnmors. AssIQNQB-TO JAMES BUImY, OF CHICAGO,

bunion irrespective of the size and shape thereof, and this without the formation of wrinkles in the plaster, which would be liable to irritate and aggravate insteadof easing the the bunion. 1

goin that the rounding of'the corners of the peta s makes the four ides or corners of the plaster recessed, or in other words, the laster comprises eight rounded corners. his is materially advanta eous inasmuch as 1t ,avoids loosening of t e plaster from the bunion which would occur if the corners were sharp 0r pointed. From this it follows that there. is no liability of the plaster working loose and rollin or forming a ridge such as would .be liable to be extremely painful. It will further be gathered from the foregoing. that my novel plaster may be formed by a die, and that therefore it may be produced quitev as inexpensively as a rectangular and imperforate plaster.

'For the pur ose of preventing deterioration of the a esive and medicinal layer 1, the plaster is preferablyv provided at the opposite side of said'layer 1,with reference to the permanent protective layer 7, with strips 2, of muslin or the like, detachably held: to the layer 1 by the adhesive quality thereof, but nda ted to be expeditiously and easily remove after theplaster is slightly heated.

Having described my invention, 'what I claim and de ire to secure byQLettersPatcut, is:

As an improved articleof manufacture, a plaster of generally square configuration aving a central portion-"and four petals grouped about and integral with the central.

pressure of a shoe vamp against It willalso be appreciated from the forecorners and being gradually reduced in width from their outeredges inward and having the outer portions of their side edges closely opposed and also. having the inner portions of their side edges recessed to form apertures adjacent the central portion In testimony whereofI have hereunto set my hand in presence of two subscribing witnesses. a
